We propose a quantum voting system in the spirit of quantum games such as the quantum Prisoner’s Dilemma. Our scheme violates a quantum analogue of Arrow’s Impossibility Theorem, which states that every (classical) constitution endowed with three innocuous-seeming properties is a dictatorship. Superpositions, interference, and entanglement of votes feature in voting tactics available to quantum voters but not to classical. (This work was conducted with Ning Bao.
